Patent EP-0264663-A2 (EP)
Inventor: UEBEREGGER HENRY
IPC: B29C53/50
Filed: 1987-09-27
Abstract: A foil strip composed of several layers is continually rolled up around an axis extending in its longitudinal direction to form a tubular body (38) in such a way that the two edges (42, 44) overlap. To effect welding, the overlapping edges are pressed together between two strips (16, 18) which are driven in a circulating manner in the longitudinal direction. The inner strip (16) which passes inside the tubular body (38) is provided with a longitudinal groove (40) which at least partly receives the region of the overlapping edges (42, 44). The longitudinal groove (40) forms the region of the seam of the tubular body (38) which is facing inward, and prevents the plastic material which is liquefied for welding from expanding as a result of the application pressure. In this way it is ensured that the material of the two edges (42, 44) is fully welded together, so that no pressed-out edge regions of liquid material cool prematurely and therefore do not adhere to the opposed material layer.

Abstract: The present invention relates to increasing the autodecomposition temperature of particular resists. The resists are comprised of structures having recurrent acid labile groups which are typically pendant to the polymeric backbone. The autodecomposition temperature of a resist is increased by selecting substituent sidechains on the acid labile group which exhibit increased stability. Sidechain structures which provide increased autodecomposition stability include secondary structures capable of forming secondary carbonium ion intermediates and having an available proton adjacent to the carbonium ion formed during cleavage. Moieties which can be used as the secondary sidechain structures include secondary alkyl, including both cyclic and alicyclic alkyl, substituted deactivated secondary benzyl, and substituted deactivated secondary heterocyclics.

Abstract: A telephone conversion device for converting a multiple line electromechanical telephone system having an electromechanical key system unit (KSU) for use with electronic telephones. Each conversion device includes a wall unit having a 50-pin connector for mating with the 50-pin connector of the KSU outlet cable, and a keystrip unit positionable on the desk of the user and upon which an electronic telephone is positioned. A slender 8-wire cord extends between the keystrip and wall units. The wall unit includes a first microprocessor which operates with a line status detector for determining the operational status of five multiple telephone lines by sensing the lamp driving signals provided by the KSU. Relays under the operation of the first microprocessor connect a selected line to a common talking pair which extends within the cord between the units for connection to the telephone. A detector detects when the receiver is off-hook. The keystrip unit includes a second microprocessor which operates with a switch scanning detector to sense the operation of five momentary contact line selection switches, each corresponding to one of the lines, and a momentary contact hold switch. Five pair of line status lights are provided, one pair being positioned adjacent to each of the line selection switches and selectively emitting red or green color light. Based upon information from the detectors the microprocessors control operation of the status lights and the relays. The first microprocessor maintains a hold-queue indicating which of the lines have been put on hold by the user and the order the lines were put on hold, and can automatically select a line for connection from the hold-queue or an idle line. The light color and whether constant or flashing   indicates if the line is under the user's or another's control, and whether on hold or in use.

Abstract: As a rule, ignition locks of motor vehicles have three positions - "Off", "Park" and "On". This provides the opportunity firstly to switch off an electronic appliance fitted in the motor vehicle on leaving the vehicle, via the ignition lock, and secondly to operate such an appliance when the ignition is not switched on or the engine is not running. As a result of the new arrangement, these possibilities are also to be retained when ignition locks are used on which a park position is no longer provided. For this purpose, the switching device coupled to the ignition lock has a logic level corresponding to the current position of the ignition lock. In addition, a bistable trigger circuit is provided which, on every actuation of the additional switching device arranged in the electronic appliance itself, alters its switching status and supplies a logic level corresponding to the current switching status. The digital signals thus obtained are linked via a switching logic which generates the control signal necessary to switch the appliance on or off. The arrangement is particularly suited to car radios. <IMAGE>

Abstract: The operation of a double diaphragm pump is controlled by a combined mechanical shifting mechanism and pneumatic pilot valve assembly. The assembly is positioned between the pressure chambers (12, 14) of the diaphragm pump in the pump housing (10) and includes a pilot member (40) switch extends axially into one or the other pressure chamber. The pilot member (40) moves axially in response to engagement by one of the pump diaphragms (28, 36). Upon engagement by a diaphragm, the pilot member (40) opens or closes a fluid pressure passageway (90) to a pneumatic pilot valve (42) which controls fluid flow to the respective pressure chambers (12, 14) associated with the diaphragm pump. A positive pilot signal is thus supplied through the entire stroke or cycle of the diaphragm pump. The pilot member (40) is not connected directly to the diaphragm or to the connecting rod which connects the diaphragms.

Abstract: The intention is to enable the channels extending through the components made from ceramic or fireproof material to be produced economically, the channels having smooth walls and edges, and a further object being to provide the channels with very narrow or small cross-sections. To this end, a mould core which corresponds to the shape of the channel to be produced is immersed in a molten lubricant which is solid at environmental temperature. The mould core, provided with the solidified lubricant, is clamped into a mould in such a manner that at least one end of the core projects from the component which is subsequently to be produced. The raw material for the component is then introduced into the mould, and heat is applied to the mould core after the component has solidified, so that the lubricant layer melts and the mould core can be withdrawn from the component.
